SHELS

Smithsonian Hectospec Lensing Survey

• redshift surveys of two of the five fields of the Deep Lens Survey

F1 centered at R.A.2000 = 00h53m25.3s, Decl.2000 = 12◦33′55′′

F2 centered at R.A.2000 = 09h19m32.4s and Decl.2000 = +30◦00′00′′.

Each of the DLS fields covers 4 square degrees.

more than 94% complete to an extinction corrected R0 = 20.2.
